Q2 Answer
1 Club
You have 11 HCPs and 4 diamonds and 5 club cards. You can open under the rule of 20 (add the number of cards in 2 longest suits to HCP total and if >20 you can open). Clubs is your longest minor and you have no 5 card major, so open 1 Clubs.
Q12 Answer
1 NO TRUMPS
As NORTH has passed and you have 9-11 HCPs, no 4 card major and a stopper in SOUTH's suit you should bid 1NT after your partner has DOUBLED.
Q22 Answer
DOUBLE
As WEST has interfered with 2S after your partner has opened 1H and you do not have hearts or spades, but have 14 HCPs, so your bid is X
